In general, will be to the following description of the present invention with reference to the embodiment and the method for some concrete structures.It should be understood that the application is intended to not limit the invention to those concrete disclosed embodiment and methods, the present invention can utilize other features, element, method and embodiment to realize.Description of preferred embodiments is for the present invention is described, rather than restriction the scope of the invention defined by the claims.Those skilled in the art can distinguish various equivalents according to following description.Usually similar elements will be represented by similar Reference numeral in each embodiment.

Fig. 1 shows first embodiment of thecooking equipment 10 that makes according to the presentinvention.Cooking equipment 10 comprisescooking container 12 and thespatula assembly 16 with inner surface 14.Spatulaassembly 16 comprisesspatula 18 and spatula driver 20.Spatuladriver 20drives spatula 18 and makes it aroundpivotal line 22 motions.Pivotal line 22 is positioned attop edge 24 places of cooking container 12.Be equipped with on thetop edge 24 andoverflow ring 26, this overflows ring and extends upward from top edge 24.Overflow ring 26 wall and can be cylindrically, or equal or be slightly larger than the hemispheroidal part of the radius ofcooking container 12 for radius.The curved inner surface that sphere is overflowed ring can make ingredient quicken to fall back in the cooking container 12.Another advantage of overflowingring 26 is as one of safeties, and it helps protecting the operator not contact or during turning be sandwiched between spatula and thecooking container 12 withspatula 18.

In the embodiment shown in fig. 1,cooking container 12 is similar with pot, almost has to be hemispheric inner surface 14.Usually,cooking container 12 uses withsupport ring 28,cooking equipment 10 is supported on thethermal source 30 on thefurnace roof 32 for example.In certain embodiments, heating element heater can be welded or otherwise is fixed in the bottom of cooking container 12.Spatula 18 is crooked spatula, and its radius of curvature is equal to or slightly less than the radius of curvature on inner surface 14.The middle body ofspatula 18 comprises camberedaerofoil 34 that circumferentially extends and theretaining piece 36 that radially extends inwardly.Can change the length of camberedaerofoil 34 and the length and the height of width and retainingpiece 36 according to operating environment, described operating environment comprises the quantity and the type of the food of needs preparation.In certain embodiments,spatula 18 should be enough thick, to save one of camberedaerofoil 34 and retainingpiece 36 or both demands used.

Fig. 2 A-2D is the simplification cross-sectional view ofcooking equipment 10, and it shows the single cycle of spatula assembly 16.Fig. 2 A shows thespatula 18 at primary importance 38 places that are inpivotal line 22 tops.Spatula 18 shown in Fig. 2 B is in thesecond place 39, just begins to contact with food or other ingredient.Fig. 2 C shows the situation thatspatula 18 continuously moves to thesecond place 41, and some part that there is shownfood 40 is still byspatula 18 supports and motion and other parts offood 40 begin to fall from spatula assembly 18.Referring to Fig. 2 D, the3rd position 42 is on theaxle 22, so thatfood 40 discharges and fall back to theopen interior 44 ofcooking container 12 from spatula 18.Can handlespatula 18 it is moved continuously counterclockwise along path as shown in Figure 2, so that turn back to primary importance 38.Perhaps, and normally preferably,spatula 18 is moved in the direction of the clock, from the3rd position 42 with swing or reciprocating mode by thesecond place 41,39 and arrive primary importance 38.

Whenspatula 18 rotates, the whole inner surface 14 of spatulascraping cooking container 12, and make the temporarily free cooking container offood 40 or other ingredient.Whenspatula 18 when the mid portion ofcooking container 12 scoops up ingredient, it forms openning also makes other ingredient fall into this openning from the both sides on the surface, inside 14 of bending.The mobile continuously mixing that helps improving ingredient of ingredient.

Usually,spatula 18 moves to suitable mixing and the rotation that position on thepivotal line 22 helps guaranteeing food 40.Yet,spatula 18 can be constituted and make food before arrivingpivotal line 22, stir or rotate.A kind of method is that retainingpiece 36 is made wedge shape or drivenspatula 18 by waving rotational motion.The another kind of more complicated less-than-ideal method of therefore possibility be to make one or more retainingpiece 36 in position stir or rotate along the path ofspatula 18 down.

Fig. 3 shows thesimilar cooking equipment 10 with Fig. 1, but it comprises motorizedspatula driver 20, also shows this spatula driver among Fig. 4.Motorizedspatula driver 20 comprises the motor 48 of driving wheel 50.Wheel 50 has pin 52, and this pin passes the slit 54 in the pivotal arm 56.Another end of pivotal arm 56 is fixed on the pivot 58, and this pivot passes gripper shoe 60.Pivot 58 is connected to the transmission mechanism 62 of the opposition side that is in gripper shoe 60 and drives this transmission mechanism.Transmission mechanism 62 drives and passes the output driving shaft 64 of gripper shoe 60.Output driving shaft 64 is connected to end ofspatula 18 and to move back and forth or the mode of swing drives spatula.Similarly oscillating motion can realize by using automatically controlled reversible electric machine.

Another difference betweencooking equipment 10 shown in Figure 3 and thecooking equipment 10 shown in Figure 1 is acooking container 12 and tooverflow ring 26 are parts separately among the embodiment shown in Figure 3, is extensions of the one ofcooking container 12 andoverflow ring 26 among the embodiment shown in Figure 1.Cooking container 12 shown in Fig. 3 and 5 comprisesdrip lip 66,overflows ring 26 to adapt to install.Drip lip 66 also helps to prevent to flow to down from the drop continuation that the outer surface that overflowsring 26 flows down the outside ofcooking container 12, and these drops that flow to the cooking container outside may burn in cooking process.In addition, for example shown in Fig. 7-8, use the type of the main body ofspatula 18, add and use theenough drip lip 66 of size can help eliminating to overflow and reduce overflowing the demand of ring as the overall dimension bending.Thering 26 that overflows shown in Figure 6 comprises otch 68, so that adapt to pivot spigot or pivot pin at any side place of spatula 18.Available making withcooking container 12 identical materials overflowedring 26, and also available other materials as high-temp plastic material or synthetic material and so on is made and overflowed ring certainly.

Usually the height thatoverflows ring 26 depends on stirring means, still, is not more than the radius ofcooking container 12 usually.Generally speaking, if makingspatula driver 20swings drive spatula 18 in the swing mode, employing then can use lower height.In addition, when moving, the swing spatula that simply spatula is centered on 360 ° of pivotal line rotations also can use overflowing of lower height toencircle 26 atmanual drives spatula 18 and operator's use.Certainly, the shape of the quantity of the particular type of food, food, spatula and style also can influence overflowing the requirement or the demand ofring 26 height.Full body type shown in Fig. 7-8 (full body) spatula can reduce greatly to overflowing the demand of ring.If use dismountable lid or ingredient distribution system, this lid or ingredient distribution system can be constituted any height that ring is overflowed in adaptation.

The surface, inside 14 of supposingcooking container 12 is parts of spheroid, and the main body ofpreferred spatula 18 is rounded and coaxial withpivotal line 22, and its radius is slightly less than the radius on inner surface 14.For example,spatula 18 can be constituted the thin slice section (Fig. 7,8) of the spherical segment (spherical sector) that looks likecooking container 12 or resemble the circular bend part (Fig. 9,10) of elongated rectangular bar or resemble small round bar.Theretaining piece 36 that overall dimension (Figure 11) or portion size (Fig. 7-10) can be set is used for collecting and promoting ingredient.Heteroidretaining piece 36 has different rotations and mixed effect, so the concrete structure ofretaining piece 36 depends on the culinary art demand at least in part.For example, thespatula 18 shown in available Fig. 7 or 8 rotates the bulk part of ingredient and needn't make these partial crushings become medium part earlier, therefore can preserve the corresponding form and the shape of ingredient.Spatula 18 shown in Figure 9 helps broken quickly ingredient and makes mixing more complete.When thewing 34 arrivedtop edge 24, it helped to prevent that ingredient from overflowing the edge of cooking container 12.Because spatula shown in Figure 9 can make the smaller portions of ingredient raise in each circulation, the required torque capacity of rising ingredient is much smaller, therefore constructs applicable to manual and little torque motor.Spatula 18 shown in Fig. 8 A has theretaining piece 36 that is equipped withporus excretorius 37; This class spatula can be used for containing the culinary art of big quantity of fluid, for example, and fried, cooking noodle etc.Separating liquid and solid cooking batching can be come by the top edge thatspatula 18 is lifted to cookingcontainer 12 inhole 37 when the culinary art circulation finishes.

Usually,spatula 18 rotates around thepivotal line 22 that passes the spherical central authorities that formed by surperficial 14 parts in the inside of cooking container 12.Surface, the inside of the scratch-off surface ofspatula 18 andcooking container 12 14 is preferred coaxial and remain tight the contact.What be used for spatula collection and promotion ingredient enters angle near the tangent line by vessel and formed two curved surfaces of spatula.Because this gap betweenspatula 18 and the inner surface 14 is very little, can controls the contact force on the cooking food batching, and reduce the possibility of blocking greatly.

The foregoing description has spherical inner surface 14.Some other embodiment can use aspheric curved surface, spheroid for example, but still to limit circular arc in each position along axis.Other curved surfaces that do not limit circular arc in each position along axis can be next adaptive by the spatula that telescopic or other variable-lengths that can change length when needing are set, and it can be swiped along the interior curve surface of cooking container.Preferred this telescopic spatula has intrinsic bias voltage and is close to the surface, inside of cooking container to force it.In some cases, only provide flexible spatula can adapt to the curved surface that does not limit circular arc along each position of axis.

For example, with reference to Figure 12, in certain embodiments,cooking container 12 can be the conventional spherical cooking container with less relativelysmooth bottom section 70, so that be stable on the smooth area of heating surface.This class cooking container also can overflowring 26 with overflowingring 26 uses or not being with.Ifsmooth bottom section 70 is less relatively, the small gap that forms between the surface 14, inside ofcooking container 12 andspatula 18 during spatula rotates can not influence the rotation and the mixing offood 40 in any tangible mode.A reason that is used for this situation is that ingredient has the trend that pushes away forward with mobile other ingredient.With reference to Figure 13, a kind of method that makes the slit minimum is to add the small circular section (rounded sector) 72 that hasspring arm 74, to adapt to the change in radius that spatula rotates.The another kind of method that adapts to flat bottom is to use the spatula of telescopic or other variable-lengths.In addition, just in time the middle body of spatula can be telescopic and/or flexible spatula element, therefore when the middle body of spatula when flat site on the bottom begins to contact, spatula is advanced with the internal table facial contour of cooking container along the whole length of spatula serially.

Only drive an end ofspatula 18 in the above-described embodiments.But as shown in figure 13, drivingshaft 76 can extend between the two ends ofspatula 18, causes spatula driver to drive the two ends of curved spatula.Figure 14 shows thespatula 18 of another style, and it is configured to adapt toflat site 70.

Figure 15 and 16 shows an embodiment again.In this embodiment, use the surface, inside 14 of shovel spatula 80 scraping cooking containers 12.Scrapingpart 82 can have circular arc with consistent with the globular arc of vessel.In further embodiments, scraping part can be made of the elastomeric material of flexibility, for example constitute by steel or plastics, and can be smooth and still with or in fact consistent with inside surperficial 14.If scrapingpart 82 is made of the elastomeric material of flexibility, also can use it forcooking container 12 with smooth slightly bottom.Because the part on 80 inner surfaces 14 of scraping of spatula, perhaps spatula 80 orcooking container 12 should be centered around vertical axis 84 rotations ofcooking container 12 centers.Figure 15 shows the operating position of cooking container circulator 86, overflowingring 26,swing spatula driver 20,driving shaft 76,shovel spatula 82 andswing spatula driver 20 when being maintained fixed, this cooking container circulator can makecooking container 12 rotate around vertical axis 84.Perhaps,spatula driver 20 can be modified as to impel andoverflow ring 26,swing spatula driver 20,driving shaft 76,shovel spatula 82 andswing spatula driver 20 and rotate, to obtain identical effect with respect tocooking container 12.

For example, the simplification of each embodiment of thespatula 18 ofassembly 16 can constitute mancarried device withspatula assembly 16, and this device can have replaceable battery or rechargeable battery.Figure 17 and 18 shows a kind of suchportable spatula assembly 88, and this assembly comprises thehousing 89 that motorizedspatula driver 20 is housed.When usingportable spatula assembly 88, needcontainer 12 is constituted andspatula assembly 88 can be mounted thereon, as the spatula assembly being mounted thereon by the receiver hole that uses qualification pivotal line 22.In addition, may need fixer to prevent that using time from movingspatula driver 20 and rotating with respect to cooking container.But portable spatula is manual operation also.

With reference to Figure 19,cooking equipment 10 andthermal source 30 can be attached in theculinary art assembly 92, this culinary art assembly comprises thehousing 91 that has built-in electronic equipment, is used to provide automatic mixing and adds thermal control automatically.In addition, Figure 20 shows theculinary art assembly 92 that combines with automatic cooking ingredient dispensedassembly 94, to produce automatic cooking device cheaply.Fully disclosed the structure and the technology that can realize this purpose in those United States Patent (USP)s above-mentioned, the content of these patent disclosures comprises in this application as a reference.
